OF PROVIDENCE,

WRIST-WAI'GI-I-STRAP CONNECTER.

Application filed April 7,

This invention relates to certain new and useful improvements in wrist watch strap connecters and the primary object thereof is to provide a simplified form of connecter 6 of this type which can be assembled without the use of solder and which can thus be more economically and quickly produced.

The invention further aims to provide a connecter of this type which is stronger and of greater durability than the soldered forms of connecters.

1n the drawing Figure 1 is a plan View of the invention applied to a wrist watch and strap;

Figure 2 is an enlarged section taken on line 22 of Fig. 1, and

Figure 3 is a like view on line 3-3 of Fig. l. y

In proceeding in accordance with the prescut invention, a blank is initially shaped to form a body 1 having-hooks 2, 2 at its ends the body being curved at 3 to conform to the watch case periphery, while the hooks 2 are formed to engage over the usual bars e secured to diametrically opposite sides of the watch case. On the side of the body 1, opposite to the side on which the hooks 2 project, the same is formed With lugs 5 having eyes in which the ends of a rod or pin 6 are received. The center of the rod 6 is formed with a circular V-groove 7. A thin tube 8 is received over the rod 6 and is formed of a length to be received in the space between the lugs 5 and to have its ends abut the inner faces of the lugs. With the rod and tube thus assembled, as shown in Fig. 3, a teat 9 is punched inwardly from the tube to engage in the groove 7. The outline of the teat is of somewhat oval form as shown in Fig. 1 and due to the thin material of which the tube 8 is constructed, the teat is resiliently supported thereby and affords 1926. Serial No. 100,310.

a spring friction grip which is forced or snapped into the groove 7. From the foregoing it will be seen that the tube is anchored by teat 9 to pin 6 and due to the ends of the tube abutting the lugs 5 the parts are held securely assembled and against axial movement, without the use of solder.

The tubes 8 are connected to the strap'cnds I ing bars, including a body havinga central part conformed to engage a side of the article and having hooks at the ends of said part to engage the bar of the article, lugs having eyes adjacent the ends of the body, a rod received at its ends in the eyes and having a central circular groove, and a thin resilient tube engaged over the rod and having its ends abutting the lugs, said tube having a teat punched therefrom to form a spring supported member which is of concave-convex cross section and which engages in the groove of the rod, the periphery of the member being connected throughout to the tube.

2. In a connecter, a body having spaced lugs formed with eyes, a rod engaged at its ends in the eyes, and having an intermediate circular groove, and a thin resilient tube engaged over the rod and having its ends abutting the lugs, said tube having a teat punched therefrom to form a spring supported member which is of concave-convex cross section, and which engages in the groove of the rod, the periphery of the member being connected throughout to the tube.

In testimony whereof I have signed my name to this specification.
